Pros:
I bought two of these cases initially with the intention to have a water-only case and a case to use for risky overland activities. Before I did anything with the cases, I tested them in water (as you should too!) I put the empty cases in a water bath in the sink with a strip of paper towel. First I did it in cold water and let the cases float for around 30 minutes, agitating them every couple of minutes to simulate splashing and some small shock. Then I submerged both cases in the water by placing a plate over the top of them to keep them underwater. Next I did the test again, but this time I used hot water. I checked the case and paper towel after each test to see if there was any leaks or other water seepage occurring. Both cases performed flawlessly with no leaks observed. Feeling confident with the testing, I affixed a square, orange float to the back of one of the cases, which would be the primary water case. About a week later, I used both the cases for my Xiaomi Yi during a vacation. The "water" case with the float was used in the ocean and on/around the beach mounted on a floating hand grip. The surf wasn't too heavy, but the case again performed flawlessly. My only recommendation is to purchase and apply the plastic Rain-X solution to the protective lens (using normal Rain-X is not recommended as it's an alcohol solution and could permanently fog or etch the lense) prior to using the case in the water as water spots are annoying and the Rain-X plastic solution will help the water bead off. I also used the "water" case&n
